Celebrity historian Niall Ferguson doesn't like President Obama, and doesn't think you should either.

That's perfectly fine. There are plenty of legitimate reasons to disapprove of the president. Here's the big one: 8.3 percent. That's the current unemployment rate, fully three years on from the official end of the Great Recession. But rather than make this straightforward case against the current administration, Ferguson delves into a fantasy world of incorrect and tendentious facts.

He simply gets things wrong, again and again and again.

Here's a tour of some of the more factually-challenged sections of Ferguson's piece.

"Certainly, the stock market is well up (by 74 percent) relative to the close on Inauguration Day 2009. But the total number of private-sector jobs is still 4.3 million below the January 2008 peak."

Did you notice that little switcheroo? Ferguson concedes that stocks have done very well since January 2009, but then says that private sector payrolls have not since January 2008. Notice now? Ferguson blames Obama for job losses that happened a full year before he took office. The private sector has actually added jobs since Obama was sworn in -- 427,000 of them, to be exact. For context, remember that the private sector lost 170,000 jobs during George W. Bush's eight years.

..."The failures of leadership on economic and fiscal policy over the past four years have had geopolitical consequences. The World Bank expects the U.S. to grow by just 2 percent in 2012. China will grow four times faster than that; India three times faster. By 2017, the International Monetary Fund predicts, the GDP of China will overtake that of the United States."

China has 1.3 billion people. The United States has 300 million people. China's GDP will pass ours when they are only four times poorer than us. That might happen in 2017; it might happen later if China's current slowdown is more than a blip. It doesn't really matter if and when this happens. There's nothing Obama can do to prevent China from catching up -- nor should Obama want to! Economics isn't zero sum. The more money China has, the more money they have to buy things from us and other countries. This is good news, and yet Ferguson treats it like a modern-day equivalent of "losing China".
